The Lakers’ Julius Randle has been doing work this offseason. Amoila Cesar, a trainer who has been working with Randle, showed off the incredible results on Tuesday (h/t Silver Screen & Roll).

Cesar’s caption:

We just hit a little over 3 weeks and @juliusrandle30 has already shown improvements in body composition and performance!! I’m having a proud moment right now but this is only the beginning. It all starts with a healthy mind, body and soul!

That all happened in less than a month with Cesar, who has a site with workout plans that are “meant to tap into your inner energy aiming to release your physical and psychological toughness.”

Cesar posted this video of one of Randle’s workouts on May 13 (warning: NSFW lyrics in video):

The Lakers and their fans should be extremely happy about this. It shows that Randle was serious when he said he wanted to come back as a “beast” next season in his exit interview in April.

Julius Randle said the front office wants him to return from the offseason”a beast coming back in incredible shape.”
